No.  A knowledgeable vendor might GUESS at the number you'd need... but 
to do it properly, a site survey should be conducted.  This involves a 
technician coming in with test equipment and measuring the signal 
strength based on the number of APs, their locations, and the types of 
antennas used.

The result will be a diagram that shows where to put the access points, 
what types of antennas to use, what areas each antennas covers, and so 
forth.

I don't remember the exact cost of the site survey, but it really wasn't 
a big deal in the greater scheme of things.  Especially if (like us) you 
have a refrigerated warehouse with big refrigeration machines that could 
interfere with the wireless coverage.  The cost of bad wifi reception is 
much, much higher.

Never heard of this.  I know our access points each have two antennas, 
and they can be disconnected and replaced with more appropriate units to 
give the best coverage.  But, I haven't heard of having a central access 
point that powers many antennas before...

I usually hear the term "coverage" when discussing this with the 
wireless professionals.  Of course, when you're in context, you can get 
by with just the word "coverage", but outside of context you might have 
to say "wifi coverage" or "wireless coverage" or something like that.
